TABULATNG-LACHINE.

To all 'whom 'it may concern:

, Be it known. that 'CHARLES E. Nicrrorison, a citizen of the United States, residing,n at Bervvymin the countyv of Cook and State of illinois, have invented certain new useful improvements in 'llabulating- Machines, otvvliich the following is a specication.

rlhis invention relates to improvements in computing machines, and more especially in that type of machine in which computa- ,tions are both indicated and recorded.

The object of my invention is to provide such a machine in which various numbers may be added or subtracted and the nurnbers, together with the results of such addition or subtraction, will be printed. These functions are obtained by the use of more practical and less complicated mechanism than in present day practice and use.

Another object is to. provide speciiic meclr anism for the f carrying out of the above taken along` the line 4 -4 of 2.

Like numerals refer to like elements throughout the dra-wings, in which indicates the casing tor the machine apertured on its top surface to permit the operation and insertion of: the operating keys 36, preferably arranoed in rows longitudinally, bearing the proper numbers in the arrangement shown, these numbers running from l to 9 from the front of the machine toward the back. These rows ofkeys, as is usual, represent columns from hundredths and tenths to millions in the embodiment shown. Each ot these keys comprises the top dislr Btl, upon which is printed orr` arried the proper number and the stem 5 (see l gs. 2 and 28) and their lower extremities extends plunger Located above the ico plunger 86 is the cern shoulder 36d 'having the inclined surface 36a. Qoosted below top 35a of Athe casing 35 are the stationary strips 37, (see Fis 2 and 5, for exemple)u These strips run longitudinally of the niacliine and ure mutually parallel. Located. above und sliding upon 'elle stationery strips 37 ure the looking ple-tes 38 provided Wili the slots 38a therein. The stems 36h extend through these slots and also tirougls. slots 37 in the stationery plates or strips 3'5"., Springs 381 extend between and are secured to the endv of tlie 85 and tno plates 38t Siinil rly, springs 38C are located at end secured to the other end of tie plates 38, tliese snrings having en end' s'ttsolied 'to the pins 37b carried by stationery plates 37, Coil springs 39 are provided with dierds, one end eseli of these springs foe .i g attached to the stationery plates 3l' Wliicli iojeot to one side of lie sliding,` or locking plates 3S. The si' 39 lieve tlieir other extremities -f the stems 56", the function or these s being` to resist movement of the earns 36 and to normally return them tshown in Fig. 2, lt will be when one of the lreys 86 is cani shoulder 36d thereof will slide tlie lo ing plate 3S on to tlie plate-37 sg @tion ofthe springs 38h, 38C, to 't der passing beneath tie Seid loelr 38, where pon tlie letter, throng?1 i gs, slide lar-eli to A ler 36d and preventing re- I:respending key to normal position.

the bars 57 will be mo'ved forward, and, as will be more fully' described below, in 'the tabula-ting ot' numbers the notched portion 57b being in engagement with its corresponding ratchet wheel 59, proper' rotation of the latter will be etiected. 'The parts and dimensions `having been properly chosen, this rotation of the indicator 58 will be proportional to the movementy ot the associated mechanism, so that the prior depressing` ot a numeral key -will result in the number corresponding thereto on the indicator wheel being rotated to the sight opening in 'the casing upon actuation ot the actuating bar. Should an indicator wheel, for example, already indicate a number when the second number is added thereto, it' the resulte);- ceeds nine the excess over l0 will be indicated by the second set of numbers ot the indicator wheel and the indicator wheel adjacent on 'the left will be rotated a distance corresponding to one num-eral thereof, thereby enabling the ready indication of the. sums ot numbers in units, tens, thousands, etc., columns.

lt will be apparent that through the arrangement and operation of the parallel bars 57, when the cross arm 6.7 is raised, the lever 67 will operate to slide the blocks 63 and associated mechanism downwardly between the uprights G-l until said parallel bars 57C engage, by means of their toothed portion 57% the ratchet wheels 60. lin this engagement movement ot the bars 57 in the manner described above will resultina rotation being imparted to the indicator wheels 58, in succession trom the lowest to the highest order, Ylhis is to enable subtraction and totaling operations to be performed, as will be inoreully described below. lt is to be noted that upon a return movement of the bars 57 to normal position the toothed portions 57b or 57 will slide over the corresponding' ratchet wheels 59 or G0 without rotating the indicator wheels, the spring detente 66 serving to produce this result. p

'lhe recording and tabulating of the numbers is accomplished in the following manner:

The bars 57 are provided wit the teeth 5'7" adjacent the line thereof on the upper side. A plurality of character wheels 7 0 are provided, one for each order ot numerals, rlfhese wheels 70-sho`wn in 26, for example-are formed with a segment of increased diameter, indicated by numeral 70g, on the outer surface ot' which is located the printing characters 70b corresponding to the numerals or characters carried by the keys 36. rl`he character wheels 70 are centrali?,r apertured. and are rotatably mounted upon. the shaft 71, secured between uprights 79 Formed on a port' :fa of the y c .L tne wheels 70 are ae 70 ,-see

man w 2 and 26,-these teeth being a suitable pitch tor engagement-and meshing with teeth 57i. A spur or lug 701 projects outwardly from one side ot-each of the wheels 70. arm 57g is carried by and attached to the extremity of each ot the bars 57. The arrangement of these parts is such that when in normal position the striker arms 57g are in contact with spurs or lugs 7 0d, while the teeth 57t are slightly out ot' mesh with teeth 70. `*Upon operating movement of the bars 57 the striker arms 57g will partially rotate the wheels 70 until the teeth 57f engage and mesh with the teeth 70. lrlhe characters 701 on the periphery of segments 70EL are arranged as shown in Fig. 26 with zerocharacter at the top and running therefrom to 9 at 'the bottom. A space is left above the zero character, as clearly shown in the drawings. Vl`he arrangement ot' these parts, and especially ol the teeth and characters is such that when the numeral key 36 is depressed and the actuating bar operated to perform the operation described above, the character wheel 70 will be rotated through an angle proportional to the size of 'the numeral to be indicated, as will be more fully described. lt will be obvious that 4when in the position shown in Fig. 2, for

example, which is normal or restposition, the. character wheels are tree to rotate in a counter clockwise position, owing` to the non-meshing of the teeth 7 0C with the teeth 57". els is well known, it is not desirable or necessary to provide numeral keys bearing the said characters, but it is necessary to provide for Zero indication and recording to the right of any integers which can be positively indicated and rerorded.

Located adjacent and to coact with the character wheels is the paper guide 75, shown in perspective in Fig. 2l. 'lhis guide comprises spaced apa-rt strips between whch the paper is intended to bc lcd. Frames 75h, 75c are secured to the strips 75, the latter being curved to form an angularly disposed bottom portion 75d, as illustrated in Fig. 2l. This arrangementprovides an entrance slot 75 and an exit slot 75f for the paper strip. The frame 75c is provided with the cross strips 75g and 75, as shown in the drawings, against which the paper strip may rest, the latter also acting to direct the paper strip upwardly after its entrance through the slot 750. 'llie arrangement ot these cross strips 75g, 75 is such as to leave an open space 75l, at which point the printing on the paper strip is accomplished, as will be further explained. llprights 70 are attached to the back of the machine casing 35 by means of clips 77, or the like. and cX- tend upwardly above the top of the machine. Pivotally attached to the upper extremities 'of these uprights are the arms 78,. between which is rotatably mounted'the paper toed A striker 4525 .ziele-jill roll 79. From this feed roll the paper strip 8O is i'fed dofvnifzir llj:, as elezu'iy shown in Fig. 8. The pivotal movement of the zur.' 78 enables them to he thrown to what l term inoperative position, as shown in Fig. 8, to prov'de for eompaetness when the meehine is not in operation. Preferably I swing the arms 78 in the direction indicated by the error: to the position indicated in dotted 1o lines in Fig. 8 when in operative position,

lAdjacent the juncture oi the' arms 108-, 108% and carried by the bottom of the cas ing 35, is the oot bearing 110, in which isoscillatably mounted a pivot plate or knife edge 111, which seats'at its upper end in a socket 108e in the lower surface or the lever 108, as clearly`-shown in Figs. 6 and 8. This construction permits lateral movement or oscillation of the lever 108, so as to permit engagement 'of either or the arms 108C, 1081 with corresponding.' ratchet wheel 99h, 100D, as will be clearly .unecistoodl 'lhe extremities of arms 1049*, 105gA normally conn tact with the-extremities of the arms 108C, 108d, respectively. .A lug 101a is carried by the ribbon 101 adjacent its end, this lug4 normally fitting in the socket 100d in the feed roll 100 when the ribbon 101 is wound therearound. rllhe extremity of 105b is closely adjacent the ribbon, and the opera tion of the mechanism is as follows:

Each time the actuating bar 55 is de-l pressed when the mechanism is in the position shown, the roller 99'may be partially rotated through the medium oir' the toothed arm 108", causing a movement of the ribbon 101b between the rollers 10Q, 103. `Arsthe ribbon approaches its extremity Jon the roll 100 the stop 101l strikes the extremity oi the arm 105, and the shaft 105'is rotated, causing the extremity of the arm 105- to torce the arm 108d to contact with the ratchet wheel 100", whereupon further actuations of the bar -108 will operate to wind the ribbon upon the roll. Each actuation of the actuating bar 55 causes the hammer or printing bar 9-1 to strike the rubber buffer strip 93, causing printing of the characters immediately adjacent thereto upon the `strip,

of paper 80, the same beinO moved upwardly in the guide member d5 after each opera-tion of. the machine.

lt is desirable in the use of these machines to have zero printed where no key is depressed when one of an order of numerals has been depressed when the latter lies toV the right of the order in which the key has been depressed. In other words, where no integer is to be set down to the right of an integer which must be set down, it is desirable to have zeros printed. F or example',

the teeth 115m.

where $1200.00 is to be recorded and added, the numeral 1 key being depressed in the longitudinal row ci' numerals from the right-hand side of the machine and the numeral Q. in the fifth order oiE numerals, it is desirable to have :tour zeros located at the right-hand of these numerals without the positive depressing of keys, `and l provide for these results inthe following manner:

actuating blocks 115 are rotatably mounted upon a shaft 116, the saine being suitably mounted in stationary parts of the l framework. Each of these blocks is provided with a tooth 1151 normally contacting with the top of teeth 70e of an adjacent character wheel 70. l. coil spring 117 is located between the front of each of blocks 115 --and the braces aan, as shown in Fig. 2, for example.v rlhese blocks are further provided with the cut-away portions 115b above Located upon the top of each loif the blocks 115 and extending over its right-hand member, as viewed from the front ci the machine, is a stud or shoulder ll'contactingfwith the top of its neighbor, as shown in Fig. 7, when in normal position. lt will be apparent that by this arrangement one of the blocks 115c may be depressed, or permitted to rotate down` wardly about the shaft 116 without interferying'with its left hand neighbors, butit will operate to depress its right hand neighbor in the absence of conidioting operations. When one of the character wheels is actuated Ito aline one of its numerals with the printer bar 94, the top of teeth 7 0e being removed from contact with spur 115, the block 115 is rotated downwardly' by means of th action of the corresponding spring 117; and, as stated above, in the absence of conflicting operations the blocks on the right-hand side or the depressed block will also be depressed through the `medium of the force of the spring 117, thereby operatinoto partially rotate their corresponding' character wheels 70. The arrangement of these parts is such that this partial rotation is just suiiicient to aline the 'first or zero character with the printing mechanism, so-that it would be apparent zero will be printed on the right-hand of any depressed numeral where aio no key will be struck in any rovi7 unless an integer is to be printed for that order oi numerals, and this arrangement permits the Zero printing or recording Without interference with the integer printing mechanism, as will be apparent.

To provide for rie-setting keys, or returning same to normal position the recording and indicatine' operations, l provide a rotatable cross shaft 120-see Figs. 8 and 9, ior example-this shaft being journeled in suitable 121. Aittached to the shaft 120 is the ratchet Wheel 122. A lever 123 is attached at its 'forward end to one of the ar 55 and L ood, u at its e. en actuato er 12J.

to engage the teeth er 22 when moved down- L tively to the shart 126, clearly shown in l 8. Carried by and attached to the shaft 2O the actuatin levers E 9 normally resting upon pins 4:6 projecting outwardly from the re-set keys 410 adgacent their loiver extremities.

The ratchet Wheel 122 is provided with an apertured hub 120E, and is preferably attached to the shaft 126 by a feather or spline 120', which will permit longitudinal movement of the ratchet Wheel relative to the shaft without adecting its engagement therewith. lt will be apparent tant when the actuating bar is depressed the lever 121` Will be moved upwardly and also the actuating arm 124 Will move backwardly past the ratchet Wheel. The arm 124, being of spring material, such as steel or the like, the teeth 12eal will slip by the ratchet Wheel. Then the actuating bar is returned to normal position, the lever 128 Will move downwardly and the teeth 124au will rotate the shaft through the medium of the ratchet Wheel, and this rotation will operate the levers 125 to depress the re-set or correction keys 40, as will be apparent, and this depression Will result in a sliding oi' the locking` plates 38 so as to release the depressed keys 36. The shoulder 4:0 of these keys 40 is ot such height as to prevent locking of the re-set keys When depressed relative to the locking plates 30. 1t will be obvious that individual. re-set or correction keys may be operated by hand to re-set any ke ys which may have been wrongly pressed, as explained above, this individual re-setting not allee/,tingthe keys in the other rows.

matt 128 is rotatably mounted in the and carries a forked arm or lever adjacent its extremity. This fork embraces the ratchet Wheel 122, as is clearly shown in Figs. 8 and 9, for example. ln its forward end the shaft 128 projects slightly beyond the casing 35, and an operlever or handle 128' is attached there- .f/'hen this handle is n the maniac bar is then depressed one less than the number of times the num? peated.

f vfil be "-marent plurality of uinbefe the mechanism described above will e erate the indicator Wheels 58 in auch vrisc the total or sum o." the numbers tabulated would be correctly' indicated by the wheels in the manner explained above. lnasmuch, hovvever, as the recording Wheels 'l0 return after each tabulating operation to normal or rest position, it will be obvious that it is necessary to provide means for printing the total or sum of the tabulated members. I utilize the indicator wheels, together with coactingr mechanism, to produce this result.

A. pair of lever arms 135 extend from adjacent the front of the machine rearwardly thereof and are pivoted at 135L 'to the casing, or other iixed support, intermediate their extremities. At one extremity each ot' these levers 135 is slotted, as indicated by numeral 1351, and at their other extremities these levers are pivotally attached at k135e to the sides 136 of the rectangular frame, generally indicated by numeral 136, comprising the sides 136a and the top and bottom 1861, 136, respectively.

Located below the levers 135 are the levers 137, pivoted at 1375L intermediate their extremities, and each having an extremity pivoted at 13W to the sides of the frame 136. A cross arm or strip 137C extends across and is attached to the other extremities of the levers 137, projecting upwardly above such levers a slight amount, as clearly shown in Fig. 15.

Coil springs 138, located below the bottom 136C of the frame 136, extend to the bottom of the casingy 35 see Fi f. 2. A key 136d entends upwardly from an is attached to the top 136b on the trame, this being what l term the totaling` key, and having the stem 136e projecting through a suitableI aperture in the'top of the machine casing. lt will be apparent, as shown in Fig. 1, that 1when the total key 136L1 is depressed the top portion ot' cross arm or strip 13Tc Will. rest adjacent the bottom of the indicator Wheels
